Verbal statements from Erik Bikis and <br />Brice Lee on 1/8/04 indicate additional irrigation will occur. <br />What will the reservoir be used for and where is the engineering to support <br />supplemental irrigation, if applicable? <br />What are the evaporation and evapotranspiration calculations? <br /> <br />"The reservoir would empty entirely most years between April and July (page 2,11)" <br />K. Beegles indicates that would not occur because <br /> <br />Inflows to the reservoir are expected to increase in the future, due to irrigation return <br />flows (page 2, 16,17) <br />Basis for claim and quantification method? <br /> <br />Stream guage and diversion records for 10-year period 1989-1998 were input into model <br />(page 2) <br />Why this period and why not the entire period of record? <br /> <br />"This BA concludes that the Long Hollow Reservoir Project may adversely affect the <br />federally endangered Colorado pikeminnow and razorback sucker based on water <br />depletions from the San Juan drainage." (page 5) <br />Problem facing proponents of reservoir project (KWK) <br /> <br />"This results in an under-delivery of Compact water to New Mexico" (page 8). <br />"The state engineers of Colorado and New Mexico disagree strongly on administration of <br />the Compact. Tensions between the states are ongoing and ultimately may result in legal <br />action" (page 9). <br />Potential explanation for not consulting with SEO (KWK) <br /> <br />"The reservoir typically will store water during non-Compact times (December 1 st - <br />February 15th) and other periods when the reservoir is in priority (page 11). <br />Were "shoulder flows" included in the model or water availability? <br /> <br />"The average annual flow in the La Plata River was reduced 480 af/yr at the Hesperus <br />gauge" (page 17) <br />Why, upper index is above all but two ditches and they are senior in priority? <br />K. Beegles - is there a ditch that can divert from La Plata above Hesperus and <br />serve Long Hollow? <br />
